Specially designed to improve the mechanical strength of the fusion splice point and ensure the reliability of the fusion; it does not affect the optical transmission characteristics of the optical fiber; the method of use is simple and safe, and the risk of adversely affecting the optical fiber during use is reduced; Monitor the splice condition of the fiber at any time; the internal seal is completely sealed, so that the weld joint has good high temperature and high humidity resistance. Features: Design fiber optic splice protection components consisting of cross-linked polyolefin, hot melt tube and reinforced stainless steel wire. 1. Does not affect the optical conductivity of the fiber. 2. Protect the connection point and increase the mechanical strength. 3. Simple operation, reducing the risk of damage to the fiber during installation. 4. Transparent casing makes it easy to see the fiber connection status. 5. The sealing structure makes the connection have good temperature and humidity resistance. Product length:60 mm Diameter: 2.25 x 59 mm Outside diameter: 3.55 x 60 mm Inner diameter: 1.5 mm Working temperature: 55 ~ 105 Shrinkage temperature range: 90 ~ 120 Tensile strength: 18 MPa Note: Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid Due to the difference between different monitors, the picture may not reflect the actual color of the item.
